This was created by the Rekai Clan. The user release chakra and then compress it around them. The chakra is compressed so tightly that shuriken, kunai, and swords break off it. This technique is a more advance version of Chakra Armor, this technique can withstand all 5 natures and very high ranked techniques depending on how strong it is. The women's version of this technique is a little weaker, but it is still effective. Chakra absorption techniques can easily counter this technique.
